We sometimes put big tags on equipment to point out things that are important that people who refuse to read the instructions might miss.
MCCs come with explicit instructions telling people to connect the bus bars between shipping splits using the provided bus splice kits. I can’t tell you how many times I have seen people use short cables to connect them (always too small) or just fail to connect them, then get angry that “the MCC is defective”…
But the factory INSTALLING something that is needed for operation, but INSTRUCTING YOU to remove it, then (ostensibly) re-install it again? That’s ridiculous IMHO.
